Abstract

Ethnobotany of medicinal plants is a form of interaction between local communities and their environment. Local wisdom in the use of medicinal plants is also shaped by the ecosystem of the local area, whether it is coastal areas, mountains, forests, deserts and so on. Raam Island is one of the islands in the Sorong Islands District of Sorong City.  The lack of support for health facilities is one of the reasons why the people of Raam Island use local plants for first aid if they are attacked by disease.  Research data or written information about ethnobotany and local wisdom of the people of Raam Island, Archipelago District have not yet been found, so this research is expected to provide scientific information to the community, government, related agencies and all parties who need it.  The method used in this research is exploratory descriptive with survey methods and semi-structural interview techniques. The selection of respondents at this interview stage was carried out using the snowball sampling method, namely a technique for selecting respondents based on key informant recommendations.  The results of the research found 41 types of plants used as medicine, 85% of the parts used were the leaves.  As a tourism development area, it is important to increase attention to local wisdom in the use of medicinal plants on Raam Island. Keywords: Ethnobotany, medicinal plants, Raam Island

Abstract

Rice is the main food crop commodity because the majority of the Indonesian population consumes rice as a staple food. Using superior seeds can help meet the increasing demand for rice due to population growth. There are local superior seeds that have not been utilized optimally by farmers in Lampung Province, namely MSP rice seeds. Since 2022, farmers in North Lampung Regency, precisely in North Kotabumi District, have been cultivating MSP rice. However, not all farmers cultivate MSP rice. The purpose of this study was to determine the comparison of production between MSP and non-MSP rice, to determine the comparison of income levels of MSP and non-MSP rice farming, and to determine the feasibility of MSP rice farming. The number of respondents was 60 farmers, namely 30 MSP rice farmers and 30 non-MSP rice farmers. Data analysis method uses income calculation using revenue structure and cost structure. Feasibility analysis of farming business uses R/C ratio. MSP rice production is lower compared to non-MSP rice production, which is 3,996.81 kg/ha for MSP rice and 4,113.44 kg/ha for non-MSP rice farming. The profit of MSP rice farming is higher than the profit of non-MSP rice farming both on cash costs and on the basis of calculated costs. The profit on cash costs of MSP rice is IDR 32,652,337.58/hectare and IDR 30,462,768.96/hectare for non-MSP rice. The profit on the basis of calculated costs is IDR 26,913,039.49/hectare for MSP rice farming and IDR 24,486,329.15/hectare for non-MSP rice farming. Based on the R/C ratio analysis, MSP rice farming is feasible to be pursued because the R/C ratio value is >1, which is 3.20 R/C ratio of cash costs and 2.31 R/C ratio of calculated costs. So that MSP rice farming has the potential to increase the income of rice farmers in North Kotabumi District.

Abstract

The use of AB mix as a nutrient in soilless rice cultivation actually prolongs the vegetative phase which results in late flowering and suboptimal grain filling. This study aims to examine the effect of ABC Mix (AB Mix + silica) and gibberellin nutrients on flowering age, growth, and yield of red rice in a soilless cultivation system. This experiment was designed using a split plot design, where ABC mix nutrients were the main plot while gibberellins were the subplots and replicated three times. The concentration of ABC Mix nutrients consisted of 4 levels, namely 750-800 ppm, 1000-1050 ppm, 1250-1300 ppm, and 1500-1550 ppm, while the concentration of gibberellins consisted of 2 levels, namely 0 ppm (control) and 200 ppm. The results showed that there was a significant interaction between the ABC Mix 750-800 ppm and GA3 200 ppm treatments on plant height (192.0 cm). The single treatment of GA3 200 ppm showed a significant effect on plant height (192.0 cm), while the ABC Mix treatment of 750-800 ppm showed a significant effect on the total number of tillers (60.03 stems), the number of productive tillers (23.03 stems), panicle length (55.42 cm), and plant height (192.0 cm). However, the addition of silica to the AB Mix (ABC Mix) and the applied GA3 was not able to accelerate the flowering phase, where the flowering time was still above 80 days after planting. This was suspected to be due to the inappropriate timing of GA3 application, while the activation of the flower meristem gene takes about 5 days after GA3 application. The inaccuracy in the timing of GA3 application actually resulted in the growth of gigas plants (twice as much as normal plants) and a low number of productive tillers (±38% of the total number of tillers).

Abstract

Dependence on synthetic pesticides for horticultural pest control has caused environmental damage and pest resistance, especially in upstream watershed areas. This study evaluated the effectiveness of the entomopathogenic fungus Beauveria bassiana for controlling major insect pests on long bean (Vigna unguiculata sesquipedalis) and shallot (Allium ascalonicum) and its indirect effects on vegetative growth. Field trials in Mojokerto Regency (June–September 2025) used a randomized block design with one factor: B. bassiana concentration (A0 = control, A1 = 106 spores L-1, A2 = 107 spores L-1, A3 = 108 spores L-1), each with five replications. Primary observations recorded pest incidence and infection by B. bassiana; supporting measurements were plant height and leaf number at 14, 21, 35, and 42 days after planting. Treatments A2 and A3 produced significantly higher pest infection rates identified in Coleoptera, Lepidoptera, and Hemiptera by characteristic white mycelial sporulation compared with the control. Reduced pest pressure in these treatments corresponded with significant increases in plant height and leaf number for both crops. Results indicate that B. bassiana at 107–108 spores L-1 is an effective biocontrol agent against multiple pest orders and can indirectly enhance vegetative vigor, supporting its integration into environmentally friendly IPM programs.

Abstract

Sargassum is recognized as a valuable source of bioactive secondary metabolites; however, quantitative comparisons of solvent-dependent extraction efficiencies remain limited. The present study rigorously assesses the extraction performance of methanol and hexane for phenolics, tannins, and major phytochemical constituents. Samples were subjected to seven-day maceration followed by phytochemical screening, determination of total phenolics using the Folin–Ciocalteu method, and quantification of total tannins with a tannic acid standard. Methanol exhibited a markedly higher extraction yield (4.23%) compared with hexane (1.13%). Furthermore, methanol extracts contained substantially greater levels of phenolics (16.13 mg GAE/g) and tannins (36.86 mg TAE/g) than those obtained with hexane, which yielded only 0.26 mg GAE/g and 0.42 mg TAE/g, respectively. The resulting phytochemical profiles highlight a clear polarity-driven selectivity, wherein methanol preferentially extracts polar metabolites, while hexane favors non-polar constituents. Collectively, these findings demonstrate that methanol is the superior solvent for obtaining Sargassum extracts enriched with bioactive compounds.

Abstract

One environmentally friendly solution for managing household organic waste is converting it into Liquid Organic Fertilizer (LOF), which contains essential nutrients for plant growth. LOF not only improves soil fertility but also has the potential to serve as an alternative nutrient source in hydroponic systems, which are increasingly popular in urban agriculture. Since chemical fertilizers such as AB-Mix are relatively expensive, LOF offers a more economical and sustainable option, although its effectiveness and optimal concentration still require further evaluation. The objectives of this study were: (1) to determine the effect of household-waste-based LOF application on the growth of pak choi in a hydroponic system, (2) to determine the optimal concentration of household-waste-based LOF for pak choi growth in a hydroponic system, and (3) to evaluate the effectiveness of household-waste-based LOF as a substitute nutrient solution for pak choi growth in hydroponics. The research was arranged in a completely randomized design with four treatments, namely P0 = 100% AB-Mix (5 ml/L AB-Mix); P1 = 50% AB-Mix + LOF (2.5 ml/L AB-Mix + 5 ml/L LOF); P2 = 25% AB-Mix + LOF (1.25 ml/L AB-Mix + 5 ml/L LOF); and P3 = LOF (5 ml/L LOF). The observed variables included plant height, number of leaves, leaf greenness, fresh shoot weight, and fresh root weight. Based on the 5% Duncan test, the treatments showed significant differences in all observed variables. Treatment P0 produced the best response and was significantly different from the other treatments. Treatment P1 resulted in higher growth than P2 and P3, although statistically it was still significantly different from P0. Nevertheless, P1 demonstrated the ability to substitute AB-Mix nutrients by up to 50%.

Abstract

National watermelon production in the last three years has decreased. The need for superior seeds to increase national fruit production. Plant breeding programs can assemble superior hybrid seeds to increase national fruit production. This study aims to determine the agronomic characters of the tested genotypes and obtain superior genotypes from the tested genotypes. The materials used were six genotypes of F1 hybrid watermelons as a result of pure line selection and four F1 hybrid varieties as control varieties. This study used A Randomized Block Design (RBD) with one factor, namely the F1 hybrid watermelon genotype, repeated twice, resulting in 20 experimental units. The results of the F-test analysis on quantitative variables have a significant effect, followed by the Duncan Multiple Range Test (DMRT) levels of 5%. Qualitative variables were analyzed using dendrogram analysis. The results of this study showed the diversity of agronomic characters from all the genotypes tested. The dominant genotype WM 2210-0616 has superior quantitative characteristics compared to the control varieties because it has large cotyledons, early female flowering, heaviest fruit, large fruit size, thick skin and flesh, high level of sweetness, percentage of fruiting plants and high fruit weight per hectare. Dendogram analysis on the qualitative variables there are two clusters with a similarity level of 72%. The results of this study can be used as material for making descriptions of varieties for registration of new superior varieties.

Abstract

The split gill mushroom (Schizophyllum commune) is an edible fungus that can be readily identified by its distinctive morphology and has considerable potential for development as a food source and a producer of bioactive compounds in Indonesia. Consequently, the establishment of an efficient propagation method through pure culture is essential. This study aimed to isolate S. commune and to evaluate its mycelial growth on different pure culture media. Isolation was conducted using a tissue culture technique from healthy and fresh fruiting bodies. The culture media evaluated were Potato Dextrose Agar (PDA), rice washing water medium, coconut water medium, rice bran medium, and corn boiling water medium. Mycelial growth rate, radial growth diameter, and mycelial morphological characteristics were used as growth parameters. The results indicated that the type of culture medium significantly influenced the mycelial growth of S. commune. PDA, rice washing water, and rice bran media supported the highest and most uniform mycelial growth. Mycelia grown on PDA and rice bran media exhibited a whitish-yellow coloration, dense and uniform growth, and a cotton-like texture. These findings suggest that both conventional and alternative media derived from locally available resources can effectively support the pure culture of S. commune, offering potential for more cost-effective and sustainable cultivation practices.
